You can find and buy High Pressure Fuel Pump / Fuel Injection Pump of high High Pressure Fuel Pump / Fuel Injection Pump – HYUNDAI H Box D (57 . The last carburetor-equipped car came off the assembly line in Since then, fuel injectors have been the primary means of getting gasoline into the engine. For the engine to run smoothly and efficiently it needs to be provided with the right quantity of fuel/air mixture according to its wide range of demands.

Then, that cylinder’s designated spark plug fires, igniting the chamber into a high-pressure, high-energy explosion.

Diesel fuel injector for Citroen Saxo D, 57 hp, 5 doors, Price: €

Mechanical fuel injection was used in the s and s by many manufacturers on their higher-performance inmection cars and sports saloons. The Factory Lightweight Legacy. The control unit is fed by a constant-pressure fuel pump. All this happens in a fraction of a second, the control unit responding instantly to changes in accelerator position, temperature and air pressure.

How Fuel Injection Systems Work

MPI systems can be sequentialin which injection is timed to coincide with each cylinder’s intake stroke; batchedin which fuel is injected to the cylinders in groups, d557 precise synchronization to any particular cylinder’s intake stroke; or simultaneousin which fuel is injected at the same time to all the cylinders.

Unlike carburetor-based systems, where the float chamber provides a reservoir, fuel injectin systems depend on an uninterrupted flow of fuel.

The injectors through which the fuel is sprayed are screwed, nozzle-first, into either the inlet manifold or the cylinder head and are angled so that the spray of fuel is fired towards the inlet valve.


Some direct-injection systems incorporate piezoelectronic fuel injectors. All modeled in 3D We’ve created the most detailed 3D ful ever produced so we can show you everything working. All diesel engines with the exception of some tractors and scale model engines have fuel injected into the combustion chamber. Fuel injection is gradually replacing carburetors in these nations too as they adopt emission regulations conceptually similar to those in force in Europe, Japan, Australia, and North America.

Retrieved from ” https: This is basically a short-term reservoir that keeps the fuel-supply pressure constant and also irons out the pulses of fuel coming up from the pump. L-Jetronic was widely adopted injedtion European cars of that period, and a few Japanese models a short time later.

The fueo lifts the needle valve from the valve seat, and fuel under pressure is sent in the engine cylinder. From there it passes into the fuel distributor, which sends a burst of fuel to each injector, from where it is fired into the inlet port. Carburetors have cuel potential to atomize fuel better see Pogue and Allen Caggiano patents.

This approach required additional sensors to measure the atmospheric pressure and temperature, to ultimately calculate “air mass”.

Bosch fuel injection systems. In the Lucas system, fuel from the tank is pumped at high pressure to a fuel accumulator. Two-stroke Four-stroke Five-stroke Six-stroke Two-and four-stroke. From the metering inejction, the fuel is delivered to each of the injectors in turn.


Auxiliary power unit Coffman starter Hydraulic system Ice protection system Recoil start. The engine had six electrically operated injectors and were fed by a semi-high-pressure circulating fuel pump system.

How a fuel injection system works

How does an electric water pump benefit your engine? Instead of injecction out in the air intake manifold, fuel is squirted directly into the combustion chamber.

A throttle position sensor TPS provides this information. The amount of fuel injected is controlled by a flap valve located in the engine’s air intake. Only air is drawn into the cylinder. This activates d75 extra injector mounted in the manifold, causing it to squirt in extra fuel to enrich onjection mixture.

German direct injection petrol engines used injection systems developed by Bosch from their diesel injection systems. All share the central task of supplying fuel to the combustion process, but it is a design decision how a particular system is optimized. This is in contrast to most fuel injection systems, which provide fuel during short pulses of varying duration, with a constant rate of flow during each pulse.

Early injection systems used mechanical methods to meter fuel, while nearly all modern systems use electronic metering.
